Under the deal, ICA Fluor will be responsible for the basic and detailed engineering for the process plants.

The company will also provide services and integration works required to increase the refinery’s distillate production capacity from 63 to 80%.

Pemex anticipates that the project will cost about $3.5bn and it will increase national production of higher value distillates through the reprocessing of products like gasoil.

ICA Fluor director general Juan Carlos Santos Fernandez said, "This project is a major step in the modernization of Mexico’s oil processing facilities, and we are proud to be in the position to support Pemex with Mexico-based engineering to advance the key goals set forth in their strategic plan."

ICA Fluor provides engineering, procurement, construction and maintenance of industrial facilities services in the oil and gas, chemical, petrochemical and other sectors.
